I want a city to be absolutely covered with scooter kids, like pigeons or rats, and if you hit just one of them, their parents run over and break your board and you can only play the game again when you purchase another 'online pass', aka a new deck, at 49.99, minimum!

Im not sure how to implement it, but many other forums have size restrictions on signature images. For height, width and filesize. A well compressed gif could very well be a low file size. [if its really short]
